steemit is not only about the money, but mainly... There are many other several reasons that keeps people in this platform, and even with all the downsides and bots and spam abuse, it still much better than anything else out there... Of course there are changes to be made, but i honestly think you are just making a prejudgement based on an experiment and not really looking into the potential of the system... Once you get enough followers here, you wont be needing to use the bots, its up to you if you do, but for personal experience i can tell you that using them is not profitable at all, mostly like any other business model, spending money on ads is most of the time not profitable at all...
